Patent CA-2557961-A1 (CA)
Inventor: HAUSMANN PETER
IPC: G06K7/00
Filed: 2005-02-28
Abstract: Method for detecting transponder-type identification media (IM) within a communication area (K-B) using high frequency inductive coupling. A short inquiry signal (ASo) is periodically transmitted from an antenna which comprises several harmonics of the HF field and has a standard power output. A response signal (ASi) is compared to a reference signal (RS) and a response signal (KS) transmitted to recognized an identification medium if the response is different from the reference signal. An independent claim is made for a read-write device for recognizing identification media within a communications area.
